Ad posters for Huawei Mate X have appeared in China. Is the device finally coming out?

Posters depicting Huawei’s upcoming superproduct have just popped up in the company’s store in China. The poster does not depict Mate X’s specific release date, but its very existence suggests that it will take place soon. Rumour is that Mate X will be released in China at the turn of July and August: release date for the rest of the world is unknown. I am curious as to what will be released first: Mate X or Galaxy Fold.
